<p>The present invention relates to a pressure sensor using an optical fiber and a pressure sensing device having the same. The pressure sensor using an optical fiber comprises: a main body casing forming the appearance of the pressure sensor; a light diffusing part installed in the main body casing, and diffusing and straightening optical signals input into the main body casing; a light focusing part installed in the main body casing, separated from the light diffusing part, and focusing the optical signals transmitted from the light diffusing part; a light blocking assembly supported by an elastic member installed between the main body casing and the light blocking assembly, installed in the main body casing, and capable of appearing and disappearing between the light diffusing part and the light focusing part. The pressure sensor is capable of having a simplified structure, thereby manufacturing and installing the pressure sensor conveniently and reducing costs required to manufacture and install the pressure sensor. In addition, the pressure sensor is capable of avoiding an effect due to an external temperature or an electromagnetic condition, thereby sensing a pressure accurately.</p> |
